FIG. 1 is a top plan view of a portion of a shoe outsole showing my new design;

FIG. 2 is a front perspective view thereof; and,

FIG. 3 is a rear perspective view thereof.

The uneven broken line immediately adjacent to the shaded area represents an unclaimed boundary of the design. The uneven broken line showing of the shoe outsole, the uneven broken line showing of other features on the shoe outsole, and the particular location and orientation of the claimed portion with respect to the remainder of the outsole are for illustrative purposes only and form no part of the claimed design.
